App1ication filed IJecember 31, 1907.v Serial No'. 408,849.

To all wzoinf itiaay concern:

Be it known that I, FREDDAvrs JACOBS, residing at Pan Paw, in the .county of Van Buren and State ol' Michigan, have invented 5 a new and Improved )leans of Car-Ventilating Systems, of which the following is a speciiication.

My invention relates'to improvements in Ventilating railway passenger cars, and has for its obj octs the provision ot a device by means of which all air entering the car shall be made to pass through a iiltering device equipped with a combination of.charco'al and Water so employed as to cleanse the air of impurities such ns (finders, dust, smoke.,` etc.; and, to

provide against sudden clianges of temperature, cold drafts, and the breathing of exhaled air, To accomplish these objects, I position in each corner oi the car aninlet stack or conduit connected with casings containing steam heating pipes, and having supply pipes running therefrom t-o the top ot the ear, through which air is. distributed to the .nterior thereof. 2 5 In order to cleanse' the air of impurities, I

provide each inlet stach with removable vertical cylinders containing charcoal of suitable sized pieces to ad-mit ofthe free passage ofvair. In the top of each stack, and di` rectly above the cylinders, is placed a detachable sprinkling device suitable for purposes of spraying the charcoal ivith watery'.

Which, in conjunction with.thesaid'eharcoah operates to purify, and in Weather to cool, the air passingtherethrough.

The use ofsteam as a medium of filtration as heretofore designed in my former Letters Patent Number 871,938, November n 26th, 1907, car Ventilating systems, would not be 40 entirely eective because the indraft of air,

through the inlet stack would carrycertain Vportions of theiilt'ering steam into the horizontal casings at the sides of lthe car, depositing therein more orfless iine cinders and dust, Which later would become dried and carried to the interior of the car. In Warm Weather, another objection to the use of steamv for filtering purposes, is, that it Would 4tend to raise the temperature of theair operated upon.4 l'

' To overcome the obj ections above referred to, I purpose to use a combination of char-v coal and Water in the manner heretofore set forth, and as is hereinafter describedl and illustrated by the following drawings; in Whieh- Figure 1 is a horizontal sectional view of a car with my Ventilating ap )aratus therein; Fig. 2 --is-a portion of a side elevation of a car showing the inlet stack in perspective; Fig. 6-0 3 is a vertical cross-section of the inlet stack in Which'lny filtering device is shown in detail; Fig. 4 is a vertical view of the cylinders removed from the inlet st-ack; Fig. 5 is a vertical cross-section of the car with (i5` relative positions of portions of the lventilating apparatus'shown; Fig. 6 is a view in perspective of the screened opening ofthe inlet stack, showing steam ra( iator, steam con necting pipes, and vent.

In all the views similar parts are designated by similar letters.

The car is represented by the character A, and in each corner thereof is positioned an inletstaclr B, the opening of whlch is through the corner-'of the car between the iloor and the roof. B is a screen `placed across the C with opening c at the top of the car, for the purpose of conveying fresh air to the interior thereof. t

F represents pipes extending erpendicu- Vlarly between the sidewalls oi' t 1e car, connecting ,the interior of the car with the exterior thereof, and having horizontal extensioiis F under the seatsbeti'veen the aisle yand. the sidefwalls'. The foul air of the car is 95 'expelled therefrom through pipes F and F.

Vvith perforated bottoms for the passage of steam therethrough Water, and having collars h and h encircling their tops to retain them in exact position Within stack B, Zt being so constructed as to receive the bottom of H, which is held in position thereby. Encircljng the interior of "stack B near the bottom, and for the purpose of holding cylinder H in position, is shoulder b2. The said cylinders are filled With vcharcoal and placed Within stack B as shown in Fig. 3, for purposes to be hereinafter described.

I represents steam heating pipes in each casing C, having connections with any source of steam supply, and suitable return pipes (not shown) for the water of condensation.

J is a steam radiatbrplaced contiguous to screen B", andfor the purpose of melting snow or sleet which mi ht otherwise clog screen B', and thus impe e the supply of air to the car. Radiator J is connected by means of a short length of pipe y" to steam pipe Z, i2 being a valve to control the how of ,and the vent.

K is a detacha tioned in each stack B directly above cylinders H and H", for the purpose of s raying the charcoal, contained in said cy inders, withvvater.

K isja ipe connected with any source of Water, suc as the engine tender tank, and is connected with sprinkler K by a short length of pipeZc", the flow of Water therethrough be- V ingccontrolled by a valve k2.

is a threaded socket to receive sprinklerl K which is made detachable thereby for the purpose of removing 'cylinders H and H.

b2 is a hinged lid for the purpose of removin cyhn'ders H and H.

j t is ap arent that the Water used in spnklingt e charcoal contained Within the said cylinders, -Will percolate downwardly throughthe charcoal, escaping through the aperture b, carrying` with it the dust and other impurities filtered from the air by the combined :fiction oi the charcoal and Water.

. It is also apparent that the action of the charcoal and Water will cool the air passing therethrough in Warm Weather. The amount of dust etc., that enters the stack B minilarger portions of flying matter.

le sprinkling device, posiinized, however by the osition of its open-V mg between the floor an roof of the car, as it is too low to catch the smoke and cinders of the locomotive, and too high to catch much of the dust raised by the passage of the train. Said openings are screened also, to reject The openings to stacks B external to screens B may be closed by shutters suitable construetion for the exclusion of dust, snow, orother matter when a stack for any reason is not in use.

The lower ends of stacks B are formed conical-shaped, with 4central openings b for the outlet of the Water from sprinkler K, and to prevent freezing of said water in either the cylinders H and H or outlet Z), I incase each stack with a jacket L having its outlet L surrounding the exitl), and connect the upper end of the jacket L with the pipe Z by means of a length of pipe Z', the flow of steam therethrough being controlled by a valve Z2.

Then the car is in service, the Working arrangement of the gatewalves D is very important, and in cold Weather, should be adhered to strictly, as a proper arrangement of these valves insures a uniform temperature throughout the entire length of the ear, for the reason that the air in the heating cases is cooler at the point of entrance and becomes Warmer as it recedes from said point, henceon one side of the car, if, the forward valve be open, the rear valve should be closed;

While on the opposite side of the car, the for- Wardl valve should be closed and the rear Valve open.

I am aware that a combination of charcoal and Water has been used to cool the air drawn into buildings for breathing purposes but this is not the purpose of my invention.
